Flyin Optronics offers a full range of Thermal/Athermal AWG products, including 50GHz, 100GHz and 200GHz Thermal/Athermal AWG. Here we present the generic specification for the 40-channel 100GHz Flat Top Thermal AWG (40 channel TAWG) MUX/DEMUX component supplied for use in DWDM system. Flyin’s 40 channel 100G Thermal AWG(100G TAWG) is designed for use within the C -band release of DWDM system. To decrease the power dissipation of the devices in different environmental conditions, the TAWG package is special designed with selection of reliable thermal plastic with low thermal conduction, and the TAWG operating temperature is controlled by using foil resist heater or Peltier TEC with thermistor temperature sensor. Different input and output fibers, such as SM fibers, MM fibers and PM fiber can be selected to meet different applications. We can also offer different product packages, inluding special metal box and 19” 1U rackmount. The planar DWDM components(Thermal/Athermal AWG) from Flyin Optronics are fully qualified according to Telcordia reliability assurance requirements for fiber optic and opto-electronic components (GR-1221-CORE/UNC, Generic Reliability Assurance Requirements for Fiber Optic Branching Components, and Telcordia TR-NWT-000468, Reliability Assurance Practices for Opto-electronic Devices).
